Hi Rave,

the code is the Mouse HID Demo from ST in ''Software Library - USB.zip''

I have changed only the scrat file:

FLASH 0x40000000 0x10000

{

FLASH 0x40000000

{

71x_vect.o (Vect, +First)

71x_init.o (Init)

* (+RO)

}

RAM 0x20000000

{

* (+RW)

* (+ZI)

}

}

Thanks for your help !!!

HIi RISC

the flash is mapped at 0x00 (User mode).

NOTE - In ''usb_core.c'' on line 730 this comment (in italian) is present:

/* sb questo e' un baco della libreria st9 */

ControlState = pInfo->ControlState; /* may be changed outside the function */

/* sb */

this is a know bug ?

thanks

RISC,

sorry, but in your zip file is not present the afx file: this s a project for ST9 and not for ARM STR7.

Have you a working RealView configuration for this demo ?

thanks
